DEVICE FOR SUPPORTING INCANDESCENT IVIANTLES.

SPECIFICATION forming part of Letters Patent No. 770,826, datedSeptember 27, 1904.

Application filed July 16, 1903. Serial No. 165.817- (No-model.)

To all whom, it may concern:

Be it known that I, ARTHUR R. SELDEN, a citizen of the United States,and a resident of Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements in Devices forSupporting Incandescent Mantles, of which the following is aspecification.

This invention relates to devices for supporting incandescent mantlesand at the same time for increasing the effective life of any mantle. 7

It is well known that the very delicate incandescent mantles commonlyused in lamps, such as the Welsbach, are easily broken and when brokenbecome ineifective.

The purpose of this invention is to prevent this breakage.

In the drawings, Figure 1 is an elevation of a burner supplied withthisinvention. Fig. 2 is a side View, principally in section, on theline 2 2 of Fig. 1; and Fig. 3 is a cross-section on the line 3 3 ofFig. 1.

The usual Bunsen tube 1 is set inside the supporting-frame 2, and uponthis supporting-frame is carried the burner-tube 3, having thewire-gauze top 4, as usual. In the present embodiment of this inventionthe top 3 has three lugs 5, to each of which is attached twohorizontally-arranged coiled springs 6' 6. The other end of each ofthese springs is fastened to the supporting-frame. The spring 6, asstated, is horizontal and is of such tension as to support the partscarried by the tube 3 with the surplus of spring strength, so that saidsprings do not when bearing their normal loads extend very much out ofthe horizontal positions. This supporting arrangement of the burner-tubeon horizontal springs gives a Very flexible and sensitive supportingmeans. From the burner-tube 3 or from the cap 4 extends a standard 7,which in the present instance is double, one such standard being on eachside, ending at the top in a book 8, on which the mantle 9 is hung.Adjacent to the upper end of the support or supports 7 is a weight10,attached to said support or supports, for the purpose of creatinginertia adjacent to the upper end of the mantle and to steady the upperend of the support or supports 7. This whole mechanism is carried by thespring 6, and consequently lateral or vertical jars or shocks to themantle-support will be eased, taken up, and absorbed by the said springs6, while at the same time the support or supports 7 weighted asdescribed, tend to remain in a definite position.

It is found in actual use that this device extends indefinitely the lifeof a tender mantle and requires extremely rough usage of the clamp tobreak the mantle.

What I claim is 1. A fixed burner and supporting-frame, a burner-tubehaving an incandescent mantle supported thereon, and ahorizontally-coiled spring supporting device attached to saidburner-tube and supporting-frame and supporting said burner.

2. The combination of an incandescent mantle, a supporting-arm forcarrying the mantle, which arm is weighted adjacent to the upper end ofsaid mantle, a fixed supporting-frame, and horizontally-arranged springsin the con; nections of said arm and said frame.
